Yuri's Powerful Draw? (AB/W31-TE23R RRR) [Angel Beats! Re:Edit]

[AUTO] When you use this card's "Backup", if the number of "Death" characters you have is two or more, choose one of your characters in battle, and that character gets +X power until end of turn. X is equal to 500 multiplied by your level. [ACT][COUNTER] Backup 1500, Level 1 [(1) Put this card from your hand into your waiting room] (Choose one of your characters that is being frontal attacked, and that character gets +1500 power until end of turn.)
